Task: Revise Regulatory Software  Geospatial Input  Geospatial Intelligence  Complex forms  Many Business Rules  National Upward Reporting / Geospatial Reports

Business Requirements  Account/password management for thousands of users  Strictly Defined Roles and Access  Remote Data Centers (run by people we’ve never met on machines we’ve never seen)  24x7 Systems with Fail-Over/Disaster Recovery  Oracle standby servers and load-balanced apache  24x7x365 DBAs at data centers

ORM1  VB with Oracle data storage (3 stored procedures)  Mapping done via ArcIMS called from VB  3 years development for point spatial storage  $5 M budget  2 Updates in 2 years  District by district deployment

ArcGIS Server Architecture

Few Moving Parts Apache MapServer CGI Oracle Web Services

Not that exciting an architecture ( but do you really want it exciting? )  Oracle Database backend - all data stored there  Apache frontend  Pl/Sql Stored Procedures - for Business Logic  Oracle Application Express (Web metadata-driven front end)  MapServer provides GIS visualization for web  MapServer provides OGC interoperability (cascading WMS/WFS and integration with ArcGIS)

One of Many (Clients) Approach Our web interface and MapServer CGI just one method to get at the data  Google Earth (kml from Oracle, wms from MS)  ArcGIS (via SDE, wms, VB.net)  Bentley MicroStation (via ProjectWise)  Others…..

ORM2  1 year development (actually around 7 months, 5 months of group meetings on peoples gripes)  $750K budget  Point / Line / Poly spatial storage  Web front end with Oracle backend (everything in oracle with mapserver cgi)  1 division (5 districts) initial deployment  All remaining districts (except 1) deployed following month

Hardware Platform  Hardware  Sun Fire 12K / 32 cpu / 32 gb RAM - for Database  1 of 40 Oracle Databases (1 gb ram allocated)  2 Sun Fire T2000 with Load Balancer / Shared with 3 others  Requirements are minimal though  Serve 50 (10 concurrent) users with Oracle XE (free) on a laptop (macbook pro) (in a vm)

Benefits  Very stable  same architecture for 6 years  Scalable  supporting ~ 1350 users, around 500 distinct users per day, 30-35K page views, 9K map views  Oracle XE is free / Apex is included  If not XE, your org probably has Oracle already  If not, Postgres / PostGIS
